Praise for Good-Bye Anxiety, Depression, Addiction, and PTSD
"Dr. Schiffer's latest publication, Good-bye Anxiety, Depression, Addiction & PTSD: The Life-Changing Science of Dual-Brain Psychology, builds brilliantly upon the foundational insights of his first book, Of Two Minds. I was thoroughly captivated by his initial explorations and am now thrilled by how this new book not only expands and updates his pioneering research in dual-mind psychology, but also integrates infrared photobiomodulation therapy to yield outstanding outcomes in the treatment of anxiety, depression, addiction, and PTSD. Dr. Schiffer's groundbreaking ideas mark a significant breakthrough in the treatment of mental disorders, providing a beacon of hope for individuals struggling with these conditions."

"What the insights of dual-brain psychology have brought to me is an increase in my level of compassion and relaxation when I am with suffering people. For no matter how badly someone is 'acting out,' I know that inside there is a more mature personality which I can relate to and address. The other thing I really like about dual-brain psychology is that it basically does not negate anyone's previous understanding of human nature or counselling techniques, but rather deepens one's understanding of why, at a deeper level, what they do is 'working.'"
Kent Barshov, MD
"Wonderfully readable and well-informed, this is the best book ever on the social and psychiatric implications of the split-brain research."
Joseph Bogen
Late split-brain colleague of Dr. Sperry
"What if you were able to get a new perspective on your emotional life that could help unlock those troubling behaviours and thoughts diminishing your life? That's precisely what Harvard psychiatrist Dr. Fred Schiffer proposes with his revolutionary dual-brain psychology. It's not just another way to think about your problems; Dr. Schiffer has developed a safe, drug-free way to literally 'see' your way to emotional balance with practical techniques that tap into one's mature and immature mindsets. He shares his latest research, his success stories from real-life therapy sessions and how you might get the benefits of dual-brain psychology at home."

Former Executive Editor, NBC News Medical Unit
"I rarely come across a book, or for that matter speak with a clinician, who truly understands the connection between anxiety, depression, trauma and the condition of addiction. This book outlines how the brain works, its impact on the mind, and how traditional psychotherapy coupled with a proven theory and strategy helps patients improve and recover. Dr. Schiffer has done it in this book for seasoned clinicians, new clinicians, as well as clinical student interns."

"Of Two Minds provides the reader with a lucent expose of the evolving understanding of the mind/brains that we all possess. This book offers new ways of understanding unconscious mental processes and their role in the activation, processing, and integration of experiences. Fredric Schiffer not only clarifies the neuroscience of our dual-brain system, but also provides numerous illustrations of how the application of this understanding can lead to healthier happier lives."
Bessel van der Kolk, MD
Psychiatrist and New Your Times Best Seller Author of The Body Remembers.
"Dr. Schiffer's book is a compelling read. It is two books in one. First, Dr. Schiffer introduces a new approach to psychiatry/psychology: an original and insightful theory. The theory deals with the idea that each hemisphere of the brain has a mind of its own, and he supports his theory with clinical and fMRI evidence. Second, and more importantly, it is a book about you, the reader. Dr. Schiffer's book gives you insight into your deepest problems. Dr. Schiffer talks about your despair, depression, anxieties, and addictions. And most importantly, his book shows how to obtain immediate relief, as well as a path forward toward a more permanent cure."
Bill Seltzer

"Dr. Schiffer rivals Freud in his revolutionary theories on understanding the human psyche. He convincingly portrays the workings of two autonomous minds in one consciousness, offering a radical new strategy in treating a multitude of illnesses, both mental and physical. I believe Dr. Schiffer's insights will be very useful for those of us wanting to optimise a harmonious, healthy balance among our body, minds, and emotions."
